Consider a distillation column that receives a feed of 500 kg/min of a mixture of benzene and cyclohexane that is 55 mole % benzene. We wish to design the column so that the distillate has a composition that is 95 mole % benzene and contains 90 % of the benzene fed to the column. Calculate the distillate and bottoms flow rates (in kg/min) and the composition of the bottoms product in mole %.

The feed stream to a distillation column is 40 mol-% n-pentane and 60 mol% n-hexane. Feed flow rate is 2500 mol/h and feed temperature is 30 °C. The column operates at 1 atm pressure and uses a total condenser. A distillate with 97 mol-% n-pentane is desired. Bottoms from the column should contain 98 mol-% n-hexane. Calculate both product flow rates

A mixture, F, of 620 lbmol/h of 46 mol% benzene (B) and 54 mol% toluene (T) is separated continuously into two products. One product, the distillate , is 98 mol% benzene. The other product, the bottoms , is 95 mol% toluene. Compute the flow rates of these two streams in: (a) lbmol/h, and (b) kmol/h. Calculate the fraction of the benzene fed to the unit that is recovered in the distillate.

A distillation column with a total condenser is separating acetone from ethanol. A distillate concentration of xD = 0.90 mole fraction acetone is desired. Since CMO is valid, L/V = constant. If L/V is equal to 0.8. The distillation column has a partial reboiler that acts as an equilibrium contact. If the bottoms composition is xB = 0.13 mole fraction acetone and the boilup ratio V/B= 1.0, find the vapor composition leaving the second stage above the partial reboiler. a)...
